🔌 Set of 2 MOSTPLUS Upstream Downstream O2 Oxygen Sensors 234-4076 234-4078 for 96-99 Jeep Cherokee Dodge Dakota - Compatible Review

BOTH WAS DEFECTIVE AND ISSUED A CEL CODE. I had to replace both before I saw that they were the cause. THERE WERE NO CODES BEFORE INSTALLATION AND ANOTHER BRAND HAD BOTH CODES SET. NONE WORKS FOR 97 TJ UP OR DOWN.

If I could give one negative star it would be -20. never worked Got a replacement unit from my parts department. Check if the engine light is off. Don't waste your money buying from oe

I bought an open box there was carbon on the underflow sensor as if it had been tested. It was in brand new working condition and has now fixed idle and acceleration issues in my 1998 Jeep Cherokee 4.0. Don't forget to check the O2 sensor fuses as well. Defective sensors lead to blown fuses.

Installed both and reset the codes, after a few minutes the codes came both didn't work. I left them for a few days and kept resetting the codes. I finally bought new ones from Napa and the code still hasn't come out and I've driven over 1000 miles on it. It's garbage. Not one is defective, but both at the same time. Don't save money.

Replaced both the upstream and downstream oxygen sensors as part of a 98 Cherokee exhaust. There is no check engine light on older sensors, I just thought it would be wise to replace it as part of the project. ONE MILE after the replacement the Check Engine light came on due to BOTH sensors failing. Cleared codes and rode again, updraft sensor continues to set CEL. ANOTHER ANOTHER FRIEND. Spend your money and buy a famous brand. You'll be glad you did.
